Karyoevolutionary Processes in Atlantic Damselfishes of the Genus Stegastes (Pomacentridae)
The karyotypic evolution of Stegastes was predominantly driven by multiple pericentric inversions (and/or centromere shifts), resulting in changes in the internal organization of chromosomes. S. rocasensis and S. sanctipauli have similar cytogenetical patterns, as well as S. fuscus and S. f. trindadensis indicating incipient evolutionary differentiation in insular species. Mapping other repetitive DNA sequences provided an exceptional opportunity to clarify chromosomal changes and their association with the evolutionary diversification of Stegastes species.
